    将字符转为unicode编码。

public class ConvertCode {   public static void main(String[] args) throws Exception{        encodeUnicode("₃");   }   //转换为unicode   public static void encodeUnicode(String gbString) {        char[] utfBytes = gbString.toCharArray();        String unicodeBytes = "";        for (int byteIndex = 0; byteIndex < utfBytes.length; byteIndex++) {            String hexB = Integer.toHexString(utfBytes[byteIndex]);            if (hexB.length() <= 2) {                hexB = "00" + hexB;            }            unicodeBytes = unicodeBytes + "\\u" + hexB;        }        System.out.println(unicodeBytes);    }}
